METALLIC RAILROAD-TIE.

Specification of Letters Patent.

This invention relates rimarily to railroad ties, has especial re erenceto metallic ties and means for securing railroad rails thereto, has forits object the construction of a durable tie and its accessories, whichcan be readily manufactured at comparatively small cost.

The invention consists in certain improvements in construction, whichwill be fully disclosed in the following specification and claims.

In the accompanying drawings which form part of this specification:Figure 1 represents a plan view, of part of a railroad tie embodyingthe invention. Fig. 2 a vertical longitudinal section of the tie and atransverse section of the rail partly in elevation. Fig. 3 a plan viewof a section of the tie, and Fig. 4 a side and end view of one of theclamps.

Reference being had to the drawings and the designating charactersthereon, the numeral 1 indicates a hollow metallic railroad tie of ourimproved construction, on the upper surface of which are depressions 2,2, one at each end forming seats or bearings 3 for a railroad rail.

cess is a vertical wall 4 thickened or reinforced to receive a bolt aswill be hereinafter described.

5 5, indicate slots in the seats 3 enlarged at t elr outer ends 6, forthe insertion of the inner end 7 of a clamping-member, in which areformed grooves 8, 8, to engage the metal in. the seat 3, and on theouter end of said member is ajaw 9 which engages the fishplate 10 of arail joint or the flan e 11 of a rail 12 at points intervening thefish-plates.

The clamping-members are adjusted and secured in position by bolts 13,the threaded ends 14 of which engage the opposite reininforced walls 4,of the tie, and the opposite ends of the bolts engage theclamping-members, as by a recess 15, 1nto which the part 16 of the boltextends, and is secured against On each end of the returning after themembers have been properly adjusted and the rail secured in position, bya cotter-pin 17, which extends transversely through the member and thepart 16 of the bolt.

The bolts 13 are provided with a head 13 and may also be provided with anut 18 bearing against the wall 4 and a jam-nut 19, or other suitablelock-nut device.

In the bottom 20 of the tie is a slot 21 for draining the tie of waterwhich may enter through the slots 5, 5, and on each side of the slot aretransverse projections 22, preferably arranged at an angle across thetie, for the purpose of preventing longitudinal creeping of the tie inthe roadbed.

The seats 3 for the rail are made wider than the base or flange of therail 12 to allow for proper alinement 0f the rail on the tie byadjusting the screw bolts 13 and the clampingmembers, and when properlyalined, the rails are secured in position by locking the bolts toprevent their accidentally turning and becoming loose.

l/Vhen signal wires are supported in the clamping-members, suitableinsulating material 24, such as hard rubber, mica or the like isinterposed between the clampingmembers and the rail to preventtransmission of the electric-current to the rail.

The tie thus constructed and equipped with rail securing devices forms acheap and advantageous means for supporting railroad rails, can bereadily made at comparatively small cost, and are durable and easilymanipulated.

Having thus fully described our invention, what we claim is-- 1. Ahollow metallic railroad-tie having depressed rail-seats formed in theupper wall thereof, permanent vertical walls at both ends of the seatsextending across the tie, rail-clamping members engaging said upper walland adjustable therein, and means separate from, but engaging sa1dclamping members and engagin the walls at the ends of said seats for adusting and securing said members in engagement with a ran 2. A hollowmetallic railroad-tie having depressed rail-seats formed in the upperwall thereof, permanent vertical walls at both ends of the seatsextending across the tie, slots in the seats, rail-clamping membershaving grooves in their sides engaging the Patented Mar. 22, 1910.

'Wall of the tie and adjustable in said upper and bolts separate from,but. engaging slots,- said clamping-members, v at the ends of said seatsand adjustable therein for securing said members: in; en-. gagement withthe rail.

3., A depressed rail-seats formed in the upper wall thereof, permanentvertical walls at both ends of the seats extending across the tie,-slots in the seats, clamping-anembers in said slots-and engaging theupper wall of the tie, and separate bolts adjustablein-the-walls at theends of" the sea-ts and engaging said clamping-members.

4. hollow-metallic railroad-tie having depressed rail seat-sformed in;the upper wall thereof, a permanent'reinforced wall at each end of saidseats, slotsin the seats, cl 'am-pin-g memb'ershaving grooves in theirsides; forengaging the upper' walllof thetie,

engaging the walls.

hollowmetallic railroadstie having;

bolts separate from the clamping members adj ustablein said reinforced.walls and en- I gaging the clamping-members.

5; A hollow metallic railroad-tie having a depression-forming a railseat at each end,

opposite slots in each seat,"a reinforced wall at each end of each seat,a. longitudinal drain slot in the bottom of the tie, and transverseprojections thereon, in combination with rail-clamping members engagingthe slots in the rail seats, and bolts for securing said membersinengagement with: a rail:
